Improved visibility for drivers in Arizona 02 Nov 2017

The 400m long Queen Creek road tunnel in Arizona is being fitted with a tunnel lighting addressable control (TLACS) system as part of a US$3 million refurbishment. The lighting system, developed, supplied and installed by Nyx Hemera Technologies of Quebec, Canada and complete with new Holophane luminaires, reduces energy consumption and maintenance needs and improves visibility for drivers of vehicles passing through the tunnel. It features an intelligent control system that dynamically adjusts lighting levels based on ambient brightness and outdoor weather conditions.

Improved lighting for the Queen Creek Tunnel, Arizona

Built in 1952, the tunnel is undergoing renovation as part of an effort to upgrade the road network in Arizona to improve security and efficiency. Work includes replacement of exterior lights at both ends of the tunnel, changes to the electrical control building and cleaning of the tunnel walls and ceiling.

“Implementation of the TLACS solution will have a positive impact on both the environment and the operating costs of the tunnel in the short, medium and long term," said Pierre Longtin, President of Nyx Hemera Technologies.
